I have a Lama v3 as well and personally I think it was a waste of my hard earned $140! That said, they're easily repairable and parts are relatively cheap and plentiful through TradeMe. Any of the guys providing parts should be able to help you source whatever you need. From experience though, they are quite hard to setup correctly if you do happen to change parts and settings around.
There's numerous threads to be found overseas on similar topics, but I'd suggest that the motor is spent or close to it. I've read that many only last between 5-20 hours (So anywhere between 50-200 ten minute flights) and that's very dependent on how well they've been treated. Numerous fast throttle changes will quickly wear them out, as will continuous running at high throttle and not allowing the motors to cool down between flights. I'm assuming you've had at least a basic look around the heli to check the connections to the motor and 4n1 receiver? Its unlikely they'd come loose but it wouldn't hurt to look. The motors are easy to replace and there are guides on the net about how to go about it.
